Abstract
A coffee grinding apparatus which includes a coffee bean grinding mechanism and a weighing device associated with the grinding mechanism to weigh ground coffee. A receptacle is associated with the weighing device and positioned below the grinding mechanism for receiving ground coffee from the grinding mechanism. The weighing device generates an actual weight signal corresponding to the weight of the ground coffee dispensed into the receptacle. A selecting device is provided to allow a user to select a weight of ground coffee to be produced by the apparatus. A dispensing assembly may be associated with a whole bean hopper, the selecting device and weighing device are coupled to a control circuit which controls the grinding apparatus. The control circuit operates the dispensing assembly and/or the grinding mechanism as a function of a comparison of the actual weight signal and the selected weight signal. As the relationship between the selected weight signal and actual weight signal approaches parity, the control circuit controls to dispensing assembly and/or grinding mechanism to controllably approach the selected weight of ground coffee.
